Vehicle wheel positioning device

Abstract

A vehicle wheel positioning device, including a frame, a jacking cylinder and two sliding sleeves fixed on a bottom plate, the outputting end of the jacking cylinder is connected with a top plate, and a belt pulley connected to a servo motor via a shaft. A vehicle wheel may be positioned via the top plate during a vehicle wheel finish turning automation processing, without switching programs for automation production of the wheel with different wheel widths and different offset distances.

The invention claimed is: 
     
       1. A vehicle wheel positioning device, comprising:
 a frame, a jacking cylinder, two guide posts I, four guide posts II, two sliding sleeves I, four sliding sleeves II, a bottom plate, a top plate, two pinch rollers, a left sliding plate, a right sliding plate, a rack, a guide rail, a fixed plate, a gear, a shaft I, a shaft II, a bearing seat, a lifting plate, a belt pulley I, a belt pulley II, a belt pulley III, a belt pulley IV, two lifting cylinders, a servo motor I, and a servo motor II, 
 wherein the jacking cylinder and the two sliding sleeves I are fixed on the bottom plate, and an output end of the jacking cylinder is connected with the top plate, 
 wherein the two guide posts I are fixed on the lower end of the top plate and matched with the two sliding sleeves I, respectively, 
 the left sliding plate and the right sliding plate, which are each connected with one pinch roller at lower ends of the respective sliding plates, respectively, are fixed below the fixed plate by the guide rail, 
 wherein the rack and the gear are fixed above both the left sliding plate and the right sliding plate, and the rack and the gear are engaged with each other, 
 wherein the shaft I, below which the gears are fixed and above which the belt pulley II is fixed, is fixed inside the shaft II by the bearing, 
 wherein a lower end of the shaft II is fixed above the fixed plate, an upper end of the shaft II is mounted with the belt pulley I, and the shaft II is fixed within the bearing seat below the lifting plate, 
 wherein the two lifting cylinders and the four sliding sleeves II are all fixed on the top end of the frame, 
 wherein output ends of the two lifting cylinders are articulated with the upper end of the lifting plate, 
 wherein the four guide posts II are fixed above the lifting plate and matched with the four sliding sleeves II, respectively, 
 wherein the servo motor I, on the output end of the servo motor I of which the belt pulley III is mounted, is mounted above the lifting plate by a flange I, driving the belt pulley I to be rotated, and 
 wherein the servo motor II, on the output end of the servo motor II of which the belt pulley IV is mounted, is also mounted above the lifting plate by a flange II, driving the belt pulley II to be rotated.
